So is it safe to say that they ripped off the Haki mechanics of One Piece with this character?
Doesn't seem unlikely to me, everyone reads One Piece in Japan, and full body Haki was shown just around the time the game was in development.
...no? It's a fuckload closer to Greed's diamond skin from FMA, if they took it from anything, it's that.

You're really bored aren't you OP?
